Inventory management for Shopify candle makers

The inventory problems candle makers run into

• Scent and size variants multiply SKUs fast. A single candle line with 8 scents and 3 jar sizes is 24 SKUs, and each one needs its own reorder point.
• Wax and fragrance oil lead times vary by supplier. Soy wax, coconut wax blends, and fragrance oils often come from different vendors, so one candle recipe depends on several supply chains staying in sync.
• Wick and vessel MOQs lock up cash. Glass jar suppliers and wick manufacturers often require case packs or minimum order quantities, so you can end up overstocked on vessels while short on wax.
• Limited edition and seasonal scents complicate forecasting. A pumpkin spice candle sells nothing for nine months then spikes hard, which throws off simple average-based reorder math.
• Fragrance oil and wax do degrade over time. Fragrance oils can weaken and wax can discolor or develop frost if stored too long, so old stock is a real cost even without a hard expiry date.

Seasonality and demand

Candle demand is sharply seasonal. Fall scents like pumpkin, apple, and cinnamon start moving in late summer and peak around autumn. Winter holiday scents and gift sets peak from November through December. Many stores see a quiet stretch in January and February before spring and summer scents pick up. Plan raw material orders for jars, wax, and fragrance oils well before these peaks, since your supplier's lead time plus your own pour-and-cure time both eat into the calendar. If you run limited editions, order components early enough that a slow supplier does not cost you the whole selling window.

Suppliers, lead times and minimums

Candle makers typically buy from a mix of specialty suppliers: wax suppliers (soy, coconut, paraffin blends) sold by the case or by the pound with case minimums, fragrance oil suppliers with per-bottle or per-case MOQs, glass or ceramic vessel manufacturers (often overseas, with pallet-level minimums), and wick suppliers sold in bulk packs. Domestic wax and fragrance suppliers often turn orders around in a week or two. Overseas vessel suppliers often take several weeks, sometimes longer around their own peak seasons. Case packs and MOQs vary a lot by supplier, so your reorder quantities need to respect each one separately.

Worked example

Say your 8oz Fireside Oak candle sells 6 units a day on average heading into fall. Your wax and fragrance supplier has a 10 day lead time, and you keep 5 safety days for delays. Reorder point = 6 x (10 + 5) = 90 units, so when stock hits 90 you need to order. If you want 20 days of cover and you currently have 70 on hand with 0 on order, order quantity = 6 x (10 + 20) - (70 + 0) = 180 - 70 = 110 units, which SteadyShelf would round up to your supplier's case pack.

Try it with your own numbers in the reorder point calculator, or size your buffer with the safety stock calculator.

A simple system to start this week

1. List every scent and size combination as its own variant in Shopify, not just one SKU per scent.
2. Set a separate lead time in SteadyShelf for each supplier: wax, fragrance oil, vessels, wicks.
3. Build in extra safety days for overseas vessel suppliers and for your busiest season.
4. Review slow-moving scents manually before reordering, since old fragrance oil and wax are a quality risk SteadyShelf does not track.
5. Confirm case pack and MOQ settings per supplier so suggested order quantities round correctly.
6. Approve draft purchase orders early enough before fall and holiday peaks to cover supplier lead times plus your own production time.

How SteadyShelf fits candle makers

SteadyShelf handles the reorder timing and quantity math across your scent and size variants, and sends purchase orders to your wax, fragrance, vessel, and wick suppliers when you approve them. It does not track lot numbers, expiry dates, or fragrance oil freshness, so you still need to rotate stock and check oil age yourself. It also does not handle multi-location transfers or bundle kits, so if you run a separate workshop location or sell gift sets as bundles, you will manage those parts outside the app.

$29/month flat, unlimited products and suppliers, 30-day free trial.

SteadyShelf is launching on the Shopify App Store. Join early access to get the install link first.
